Data assimilation with soft constraints (DASC) through a generalized iterative ensemble smoother
Luo, Xiaodong; Chalub Cruz, William (Peer reviewed; Journal article, 2022)This work investigates an ensemble-based workflow to simultaneously handle generic, nonlinear equality and inequality constraints in reservoir data assimilation problems. The proposed workflow is built upon a recently ... -
Hyper-parameter optimization for improving the performance of localization in an iterative ensemble smoother
Luo, Xiaodong; Chalub Cruz, William; Zhang, Xin-Lei; Xiao, Heng (Peer reviewed; Journal article, 2023)This work aims to help improve the performance of an iterative ensemble smoother (IES) in reservoir data assimilation problems, by introducing a data-driven procedure to optimize the choice of certain algorithmic ... -
Joint History Matching of Multiple Types of Field Data in a 3D Field-Scale Case Study
Chalub Cruz, William; Luo, Xiaodong; Petvipusit, Kurt Rachares (Peer reviewed; Journal article, 2022-08)This work presents an ensemble-based workflow to simultaneously assimilate multiple types of field data in a proper and consistent manner. The aim of using multiple field datasets is to improve the reliability of estimated ...
